Max Goldberg, New York, N; Y. Application May 10, 1937', Serial No. 141,8'41

This invention relates to a machine-for filling the casings of such articles as stuffed dolls, toys, etc, with fibrous materials such as cotton, cork,

or straw.

6- Anobject of this invention is to provide a filli'ng machine comprising a hopper superimposed over one end of a linked filling material carrier and having a nozzle-in alinementwith the carrier 4 at its other end.

Y6 Another object of this invention is to provide asprocket chain carrier, the links of which have integral angularly' extending pusher arms and the said hopper having openings in two-f its lower side walls permitting said arms to pass through 3 the lower portion of said hopper'and carry portions' of filling material therefrom to" the nozzle endof the sprocket chain andpush the material into the-casing to be'filled.

Another object of this invention is to design the sprocket chain-carrier so that when a pair of pusher arms deliver a batch of filling material into thenozzle they will immediately swing back wards from the nozzle andmove with their coacting chain linksbelow the nozzle.

Another object ofthis invention is to provide a supportingtrackbelow the sprocket chain so as to cause the pusher arms to move in a fixed i'ngsand pointed outin the claims which form part or this specifi'cation.

wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a plan view of the filling machine.

Figure 3 is a fragmentary cross-sectional view, the section being taken as on line 3-3 in Figure 1.

Figure 4 is a fragmentary cross-sectional view, the section being taken as on line 4--4 in Figure 1, the sprocket chain and pusher arms being removed.

Figure 5 is a cross-sectional view, the section being taken as on line 55 in Figure 2.

In the illustrated embodiment of the invention, the numeral I0 indicates a casing filling machine comprising a frame I I having an elongated bed or operating table I2 at its upper surface. The table I2 has two parallel longitudinal slots I3, I3. Secured to the table I2 and in superimposed rela- With the above andother objectsin view, the

A sprocket chain I5 having pairs of pusher arms I6 fixed in right angular relation to altern'atelinks is mounted on an idler sprocket wheel IT and a driving sprocket wheel I-8- below and in parallel relation with the operating table I2 and so that the pusher arm's extend through the slots I3 above the operating table. A track I9 has been secured below the operating table I2 and provides a support for the. links of the sprocket chain I5 and causes the pusher arms I6 t'o-operate in a fixed path parallel with and above the operating table l2.

The idler sprocket wheel I! is secured to a shaft 20 rotatably disposed within bearings 2!. The bearings 2I are suitably supported in the frame II as by means of angle irons 22. The driving sprocket wheel I8 is secured to a drive shaft 23 rotatably disposed within bearings 24. The sprocketchain I5 is also'mountedon'an idler sprocket wheel 25 which is secured to'a' shaft 26 disposed within bearings 21'.

The sprocket wheel 25 has been positioned at a lower elevation than the sprocket wheels 'I 'I and I8'so a's toc'a'use'the sprocket chain I5 to move downwardly away from the bed I2 and carry the pairs of pusherarins I6 to a position below the nozzle; As shown'in Figure2, on'e'end 29of the nozzle" 28" terminates substantially in line with the pitch circle 38 of the'sprocket' wheel I'Band when a pair of pusher arms I'BfdeIiver'sa batch of filling material into the nozzle 28' the resistance of the compressed material in'the nozzle stops the forward motion of the said pusher arms and causes said arms to swing about the rear pivot in the" link" with which it is" integrally connected. Since the sprocket 25 is an idler the inclined portion of the chain is loose and under no tension. The said pusher arms are therefore free to swing backwards and clear the nozzle while following a portion of the said pitch circle in its movement below the bed I2. The sprocket chain I5 is endless and with the pusher arms extending all around the chain forms a travelling conveyor 30.

The hopper I4 has two slots 3|, 3|, in the rear ,side wall 32 permitting pairs of pusher arms to pass therethrough. The hopper also has an opening 33 of nozzle size in the side wall 34 permitting the respective pairs of' pusher arms and batches of filling material to pass through in its passage to the nozzle 28.

As shown in Figures 2 and 4, the hopper I4 has perforations 35. These perforations may extend throughout the entire surface area of the hopper or be limited to a portion thereof and serve to provide an outlet for air from. the air blower of a processing machine (not shown) by means of which the material is fed to the hopper.

The opening 33 in the hopper I4 leads into an elongated covered passageway 36 into which the nozzle 28 extends. The pusher arms I6 project normally from the linked member l and extend substantially to the upper elevation of the nozzle.

In operation, the processed filling material is fed into the hopper l4 and the sprocket wheel [8 is rotated continuously in the direction shown by the arrow to cause the linked member l5 to move in a linear direction as guided by the supporting track l9. Pairs of pusher arms [6, l6, grip batches of filling material from the hopper and deliver it into the nozzle 28 and into the casing 31 of a casing to be filled or stufied.

In accordance with the provisions of the patent statutes I have described the operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means within the scope of the appended claims.

I claim:
